To all whom it may concern:

- citizen of the United States of America, residing at the city and county of Denver and State of Colorado,

have invented a' new and useful Roofing-Cleat, of which the following is a specification.

.My invention is for a new double joint lap cleat for securing roofing sheets to the roofs and sides ofbuildings; and the objects of my invention are: First, to provide a double joint lap .blnding and clamping cleat thatwill shed water from the upper sheet of a roof, and that will prevent water backing upon the lower sheet into and through the lap, joint between the And second, to provide a double joint lap binding and clamping cleat, that covers the edge of the lap joint between the sheets, and that is of such a trussed form of crosssection that when secured in position by nails on a roof of a building, that the edges of its flanges embed themselves in the lapped sheeting. I attain these objects by the mechanism illustrated in the accompanying drawings, in which: Figure 1,is a perspective view, ing portions of two sheets of roofing material, the overlapping edges of which are secured by the improved clamping cleat, said cleat being provided wlth raised nail-receiving caps. Fig. 2, is a view similar to Fig. 1, but showing the cleat provided with depressed or counter-sunk nail receiving caps. Fig. 8, is an enlarged vertical sectional view on the line 33 of Fig. 1. Fig. 4, is a similar sectional view on the line 44 of Fig. 2. Fig. 5, is an enlarged perspective view of a portion of a cleat of the style shown in Figs.

1 and 3. Fig. 6, is a perspective vlew of a.

cleat in which the nail receiving caps are omitted. Fig. 7, is a perspective view of the end portion of a cleat, the metal being pressed so as to close the end of the cleat.- And Figs. 8 and 9, are views illustrating the manner of securing roofing sheets to the roofs and sidings of buildings, the sheets being shown at right angles to the pitch of the roof and in the same direction as the pitch of the roof.

Similar letters of reference refer to similar parts throughout the several views.

Referring to the drawings, the numeral 1 designates a cleat embodying my invention. This cleat may be made of metal, wood or of any other suitable material.

My invention, however, contemplates a cleat thatis designed to be placed over the side edge of the top layer of the roofing sheeting, and that rests against the lower layer, as well as against the top layer of the sheeting. This arrangement requires anovel and special form and arrangementof cleat, and I have especially invented and designed it in such a manner as that its opposite side edges are olampingly indented in the sheetings of both layers of the sheeting, and the side edge of the or bottom sheathing by virtue of its indentation into the bottom sheeting when nailed tightly-to the roof boardsprevents water from backing up into and through the overlapping joint between. sheeting.

My improved double joint making cleat comprises narrow strips of metal or other suitable material, but preferably made of galvanized iron, that comprise acentral body portion 2, which is preferably made fiat, and on each central body portion bevel flanges 3 and 4: are formed, th'e'edges of which form the sheeting indenting and clam-ping edges of the cleat; These flanges, however, are made of different angles, the angle 3 being the flatter, and it forms a downward sloping angle from the central body portion of the cleat, that is of sufficient bevel to allow its edge to embed itself into the upper sheet, and also -to allow water to run readily up over it and the cleat from the upper sheet. The flange 4 is made to extend at a sharper downward angle to the central body portion of the clamp than the flange 3, in order that its edge may extend down over the edge of the upper sheet, and rest firmly against and embed itself into the surface ofthe lower sheet of the roof sheeting, and the edges of the flanges when the cleat is made of galvanized iron of about a thirty-second-of an inch in thickness, are sharp enough to be embedded into the roofing sheets" when nailed the two layers of on the sheeting on a roof by roofing nails,

which is the means employed to secure them to the overlapping joints of the sheeting sheets. To prevent the edges sinking into the sheets too far when very thin galvanized iron is used, the edges may, if desired, be slightly turned or rolled to one side or flattened, as shown in Fig. 5.

I preferably provide my improved cleats with nail receiving holes, which are punched of the opposite sides of the cleat that rests on the lower ,is necessary to firmly secure the cleats to the roofing sheet, and at the same time clamp the overlapping joints of the sheets tightly together. I have found in practice that the cleats should be nailed to the sheets and roof about every three inches of their length, and I preferably provide them with nail receiving holes placed at that distance apart. Inasmuch, however, as my improved cleat covers the edge of the top sheet at its lapping joint, I preferably position these nail receiving holes out of the center of the width of the cleat, and nearer to the upper flange 3 of the cleat flange 4.

The central body portion of my improved cleat where the nail receiving holes are formed, may be made flat if desired, and the cleat madev of a thickness of metal that will permit the nails to be driven against the cleats without tending to flatten and spread out or apart the side flanges of the cleat opposite to the nail receiving holes. I preferably reinforcingly tIIISS thecleats around the nail receiving holes, in order to strengthen the cleats at these points, and while there are a number of ways in which this feature of my invention may be carried out, I preferably arrange it in the following manner: Around each nail receiving hole at the time the holes are punched through the cleats,-I forma cap portion .6. This cap portion may be a depressed cap portion, 'as shownin Figs. 2 and 4-, or a raised cap portion as shown in Figs. 1 and 3, which is the preferred construction when these cap portions are used. This cap portion comprises a circular button-like portion, that is pressed to project from the metal. This cap is preferably placed centrally in the width of the central portion of the cleat, as shown in Fig. 3, and the nail hole is punched through the center of the cap. The opposite ends of the cleat strips may be ofany desired shape such as square, and the side flanges are of the same form as the cross section of the cleat, or the ends may be rounded, or they may be turned down to close the opposite ends of the strips.

The application of my improved cleat to sheets of roof sheeting and its operation in securing their overlapping edges together and to the boards of the roof or side of a building to form water-tight joints between the sheets, is as follows: Each sheet is laid than to its lower covering cleat with their flange 4 substantially up against the edge of the upper sheet, and the cleats may be made'in lengths of from several inches to several feet, most of-them being made in such lengths as the sheet metal or material can be obtained of the longest lengths in, but cleats made in different lengths are, an advantage in finishing out the ends of a sheet at the ends orsides of roofs of buildings, and they are laid end to end along the overlapping joints of the roofmg sheets across the roofs or sides of buildings, and are firmly and solidly nailed to'\ the sheets, the heads of the nails being driven down tight against the cleat to force the edges of its flanges to slightly embed themselves into' the surfaces of the roofing sheets, which acts to make a double joint on the sheet, one

the flange 3 embedding itself into the surjoint being made by the edge of face of the top sheet, and the other joint being formed by the edge of the flange't embedding itself into the surface of the lower sheet, while the entire pressure of the cen tral portion of the cleat is forced down against the edge portion of the top sheet, andit is pressed and clamped down against the lower sheet with a pressure that acts to securely bind the overlapping edges of the sheets together tight enough to form a water-proof joint between the sheets and at the same time the nails firmly secure them to the roof or side boards of the building.

My invention provides a strong rigid lap that will bind and clamp both the lower and upper sheets against the building, and also bind them togethe: and secure them to the building. 1

Having described my invention, what I claim as new and desire to secure by Letters, Patent, is: 1

A cleat for lap-joints of sheet-roofing, comprising a metal strip having its edges bent downward to form two longitudinal flanges, one of said flanges being bent at an abrupt angle, whereby it may extend close to the lower edge of the upper sheet, and of such width that its edge may engage the surface of the lower sheet, being bent at a less angle, whereby its edge may engage the surface of the upper sheet, said strip having perforations therein so arthe other flange ranged that nails driven therethrough will
